Those people see the too much youtube pranks and think it's going to have the reaction as on youtube.
Do they realized most are staged videos and the people are told in advance what the joke will be about? I was just reading about a man breaking a girl's heart by doing an ''I cheated on you'' prank or a woman doing a ''My boyfriend beat me up'' prank on her family. They had the same excuse of trying to copy it from videos.
It's only funny if the people have a history of pranking each other so much or the person is on the joke. Otherwise the reaction will likely be a break-up, heartbreaks or an angry crowd.
